Product Advantages:
1. Cable advantage, the fourth generation of high-speed cable with shielding, the use of high-quality connectors, 

high-frequency support for PCIe 4.0 x4 64G/bps / PCIe 4.0 x1 16G/bps stable transfer.

2. Advantage of cable length, from 5cm to 1m can be accepted to order. 

This adapter cable, low cable impedance, 60cm or less cable length can stably support PCIe4.0 full speed.
3. Differential signals without over-hole design, there is no parasitic capacitance and parasitic inductance 

of the signal attenuation interference problems, and will not have CAF micro-short phenomenon, product durability.
4. PCB selection of high-frequency, low resistance of high-quality materials, PCB precision workmanship, 

PCB using high TG plate, copper thickness thickened to 1oz. 

Gold-plated gold finger sufficient conductivity can reduce oxidation and rust impedance caused by elevated dead and broken sound problems.
5. The product selection of wire is very durable, the use of metal at the point of welding thickness of up to 3mm PCB spacer protection, 

and lock the screws and hexagonal nut fastening, the product is strong and reliable pulling, anti-interference, there will be no broken line off the nail problem.
6. PCB dwarfing and fat design, dwarfing will not be stuck to the graphics card, fat and long design to make the board easier to install, reduce the chance of damage.

Summary of technical questions:

What is the quality of the wire? Is it shielded?
Yes, there is metal layer shielding with advanced EMI shielding conductive polymers, 

a new type of material used for EMI shielding and flat cable design. 

This technology allows each cable to be completely covered by the 

EMI shielding of the conductive polymer to prevent incoming or outgoing emissions of electromagnetic frequencies, 

minimise interference and performance degradation, and reduce the weight of the cabling.

Thickness of wire? Is it soft? Can it be bent?

Yes, the cable is the fourth generation of PCIe cable, the thickness of the black model is 1.3mm, 

the thickness of the silver model is 1.4mm, the cable can be bent or folded, does not affect the use.
